FROM NEXTMOVIE: Remember how Ryan Gosling is making his directorial debut with "How to Catch a Monster," a script he penned himself, which follows a young boy who discovers a road to an underwater town? Well, rumor has it that Ryan has cast his another lead (in addition to already announced Christina Hendricks), and it's a lovely lady he knows well—both on and off screen. Have you figured it out yet? Why, it's his main squeeze, Eva Mendes! Boy, it's rough being a Gosling girlfriend.
